. Easton,

Be it known that I, FRANKLIN C. M nLER, a citizen'of the United States, residing at inthe county of Northamptonand State of Pennsylvania, have invented a new and 'useful Hood-Lookv for Automobiles, of

which the following is a specication.

The invention relates to a hood lock'for' automobiles and other motorvehicles 1 and minor details of'construction,

j out departing from The object of the present invention isto provide for automobiles and other motor vehicles a simple', eiioient and comparatively Ainexpensive lock, adapted to `be lreadily applied to an automobile -or analogous vehicle,

and capable' of securely locking the hood on.

the frame or chassis-to-prevent access tothe motor by a thief or o-therunauthorized person.

' With these and other objects 'in view, the

invention consists in the construction` and novel combination 'of parts hereinafter fully described, illustrated' lin 'the accompanying.

drawing, and pointed outin the claims hereto appended; it being understoodl that various changes in the form, proportion, size.

within the `scope of theclaimsfmay be resorted to with? the spirit or sacrificing anylof thev advantages o f the invention.

Athedrawng z-F-igure lis aside elevation of a portion of an automobile provided withhood locks, constructed-.in accordance .withthis invention. Fig. 2 is ian enlarged detail' elevation of the hood lockiand a por.-

ltion of the hood and frame of the car or machine. Fig. 3 is av vertical sectional view, on the line 3-3 ofFig. 2. Fig. 4 is a simi-l jlar view on' a slightly enlarged scale, the

the lock.

outer supporting sleeve being in' section. Fig. 5.is a central verticals'etional viewof Fig, 6 is a detail'prspect-ive view ofjthe outer supporting .sleeve- 'Fig. 7- is a i `detail view of the tubular bolt or sleeve, the

.locking .arm being detached. Fig. 8 is a horizontal sectional view onthe `line 8-8 of F ig. 4.

'Like numerals 'of reference designate cor?- responding parts'in'alljthe figures of the drawing.

'In the,accompanyin'g drawing in which is" illustrated the preferred embodiment of the invention, l designates fal tubular bolt or sleeve rotatably mounted on the lower end of a vertical cylinder 2 and carrying alookfijngqarm 3, having an L-shaped extension comprising'a vertical portion 4 and a hoi'i- .v

.upper the plane of the horizontal portion of the eX-.y tensicn of the arm .3 of the' bolt, which,

when 'turned by the means hereinafter de' zontal -terminal engaging portiony 5f. V*The locking arm 3 extends horizontally from the bolt 1, and the vertical portion 4; is connected at its'lowerl end to the 'out-'er terminal of the arm 3, and at its upper end to the inner terminal of the arm 5.A The cylinder 2,-

which rotates within a lock casing 6, is provided with the keyhole or slot 7 for the reception ofa key 8 foroperating co'actin'g tumbler pins 9 and 10, the pins 10 being pressed or urged inwardly by vsprings 11,

l2 of the lock housed in an offset chamber casing 6. The lock casing 6-is mounted in a vertical supporting sleeve 13, provided at its upper endwith .an integral attaching flange 14, secured, bybolts. or other "suitable ,fastening means to the lower face ofthe upv Aper flange 15 of a channeled bar' o'r'beam 1.6, `constituting-one of the members of the frame lorchassis of the automobile. The hood lock :is located within the' groove or channel 17 ofA the bar or beam` 16, "and the hood 18 rests upon'the upper face of vthe beam' v,16, 'being' preferably provided with an outwardlyf eX- tending horizontal flangel, as clearly illus- L .trat'ed in Fig. 3`of the 'drawing- The hood is` equipped. at its inner face 'with a depend' ing approximately Lshaped engaging meiik i y ber orlkeeper 20, consisting ofa vertical por;-

tion anda horizontal portion, the vertical portion being secured at itsupper end to the inner portion being located below the plane ofthe flange 15 .of the beam 16, and `below scribed, carries the lL-shaped extension of its arm 'into and out of engagement with the Lfshaped. keeper or member 20. f The upper horizontal portion 5 'of the -arm lof the bolt is carried to a positionabove the horizontal portion of the keeper=f20, whereby'fthe'hocd is locked against upward movement and' is effectually, prevented fromvbeingA removed by, at thief or other A unauthorized person. VThe hood locks'are preferably 4arrai'iged in face of the hood, and the horizontal ifoo pairs', 'asin'dicate'd iiLFig. lof the drawing, i

vbut any.' other arrangement may, of course,v

be employed The supporting* sleeve 13- is provided in its upper portionl with 'a vertical slot 21, receiving the-offset chamber 11 kof the lock casing and haviiiga .branch 22 extending through the extension flange. The'slo-t 21 4and the branch 2 2 enable the lock` to be readily fitted in the supporting sleeve in assembling the parts. -The outer sleeve eX- tends to the lower end of the tubular bolt or sleeve l, andforms an outer casing forthe same. .projects below the lock casing 64 to receive the tubular bolt or sleeve 1, and it is adapted to make one complete revolution so that the key 8 can be inserted to operate the lock and removed after the lat-ter is in locking position. The bolt, however, is intended to turn through approximate-ly a quarter of a revolution to carry its extension to and from the keeper. a transverse arcuate slot 23 into which extends a stop 24, preferably'in the form of a screw secured to the rotary cylinder. The upper or inner end of the tubular bolt or sleeve is provided with a projection 25, adapted to engage approximately diametrically disposed shoulders 2 6, formed by'a recess 27 in the lower end of a lock casing. The project-ion 25 and the recess 27 are of a length to permit only the proper desired rotary movement of the tubular bolt or sleeve, while the slot 23 and the screw 24C constitute a lost motion connection between the cylinder and the bolt. The tubular sleeve or bolt is provided in its lower portion with a transverse opening 28 for the reception of the inner portion 29 of thek locking arm 3, which is threaded to engage the threads of the opening 28. The threaded connection between the locking arm and the tubular bolt or sleeve enables the lockingarm to be applied to the bolt after the parts of the lock have been assembled, and the bolt is also provided with a central threaded opening 30, extending upwardly or inwardly from the .lower end of the bolt and intersecting the transverse opening and adapted to receive a setpscrew 3l for clamping the.

locking arm to maintain the same in proper position. The outer supporting sleeve is provided at its lower end with a transverse slot 32, through which the locking arm of the bolt extends and which permits the same to swing cylinder. The' slot 23 is of a length to permit the desired-independent .rotary movement of the cylinder,'and when rotated the stop 24 is carried along the slot 23 from one end of the same to the other end thereof, and through its engagement with the adjacent end wall actuates the bolt during the remainder of the rotary movement of the cylinder. A rotary movement of the cylinder in the opposite direction carries the stop or projection back through the slot '23 and into engagement with the other. end wall thereof, thereby rotating 'the sleeve in the reverse direction from which it was rst rotated. When the hood is locked, it is impossible for an unauthorized person to obtain access to the engine or motor.

The lower end of the cylinder For this purpose the bolt -has horizontally when actuated by thel sleeve secured, to

The lock casing and the cylinder extend above the att/aching plate of the outer supporting sleeve and pass through an opening 3 3 in the upper flange 15 of the channeled beam or member of the frame of the car, andt-he upper end of the lock is normally covered by a cap plate or closure 34, secured t-o the channeled bar or beam 16 by a pivot 35, and movable to and from a position over the top of the lock. The cap plate or cover is adapted to exclude dust, dirt, waterand other accumulation from the lock to prevent the same from ,becoming clogged and inoperative.
